Sarsen Stones

The “Druidical” sandstones of Wiltshire and Berkshire are so
called. The early Christian Saxons used the word Saresyn as a synonym
of pagan or heathen, and as these stones were popularly associated with
Druid worship, they were called Saresyn or heathen stones. Robert
Ricart says of Duke Rollo, “He was a Saresyn come out of Denmark into
France.” Another derivation is the Phoenician sarsen (a rock),
applied to any huge mass of stone that has been drawn from the quarry
in its rude state.

These boulders are no more connected with the Druids than Stonehenge
is (q.v.).
